同生断层和微构造对油井产能和剩余油分布的影响

摘要

P油田已进入高含水开发阶段,因此寻找剩余油富集区是保证油田稳定生产的关键.通过分析P油田同生断层附近和微构造区油井的产油能力和剩余油分布状况,研究同生断层和微构造对油气聚集的影响.综合研究认为,P油田同生断层附近和微构造中的正向微构造类型区油井产油能力强,剩余油富集,表明同生断层和正向微构造是P油田剩余油富集和分布的重要类型.%As P oilfield enters into high water cut stage, seeking remaining oil has become the significant factor for keeping stable production in P oilfield. The influence of contemporaneous fault and microstructure on hydrocarbon accumulation is investigated by analyzing the oil well productivity and remaining oil distribution nearby contemporaneous fault and within microstructure in P oilfield. Integrated research indicates that it has high well productivity and enriched remaining oil nearby contemporaneous fault and within positive microstructure. Therefore, contemporaneous fault and positive mierostructure are important zones for remaining oil accumulation and distribution in P oilfield.
